the area of a rectangle is A=a%2Ab

with side lengths of 2a%2F5b units and 3b%2F8 units the area of a rectangle will be:
A=%282a%2F5b%29%2A%283b%2F8%29
A=%282a%2A3b%29%2F%285b%2A8%29
A=%28cross%282%29a%2A3cross%28b%29%29%2F%285cross%28b%29%2Across%288%294%29
A=%28a%2A3%29%2F%285%2A4%29
A=3a%2F20
A=%283%2F20%29a
A=0.15a
